Figure 5. MonoS cation-exchange chromatography of EBNA1.
A) The chromatogram resulting from further purification of the Ni-NTA eluate over a MonoS column. Absorbance at 280 nm is shown as a solid black line. Absorbance at 260 nm is shown as a dashed black line. The salt gradient utilized is shown as the slanted black line. B) SDS-PAGE (Coomassie stained) showing EBNA1 purification by MonoS chromatography. FT is flowthrough. MW is molecular weight markers.
